Constructed with 100% polyurethane on all sides, this high-flow, oiled OE replacement performance filter outflowed the stock filter by 33% resulting in improved horsepower and torque. The Pro 5R air filter uses five layers of progressively finer mesh cotton gauze media to provide maximum airflow for best performance results. Washable and reusable for multiple cleaning cycles, the tall, open, evenly spaced pleats provide excellent dust holding capacity for a longer service cycle between cleanings. An integrated urethane bump seal insures tight, no leak seal over the life of the filter.

Rounded Open Pleats:
aFe performance air filters use a rounded pleat design which produces more usable filter surface area for increased flow and greater dust holding capacity.

Progressive Bump Seal:
This pliable sealing surface conforms to even the most uneven filter housing. This design eliminates the use of gaskets or sealants. The soft urethane construction always goes back to its original form so you will never compress the bump seal. This makes for a perfect filter fit and sealing surface every time.

Full Urethane Housing:
aFe Power performance air filters are constructed using full 360 degree urethane frames. This construction allows for a proper OE style fit with excellent filter strength.
